Description

Technical Field

[0001] The present invention relates to atomization technology, and more specifically to an atomization device and an electronic atomization device.

Background Art

[0002] The heat-not-burn cartridge includes a tobacco part, a hollow cooling part, and a mouthpiece part. When the tobacco part is heated, it can generate atomized smoke that can be inhaled. The hollow cooling part blocks the transfer of heat from the tobacco part to the mouthpiece part to prevent the deterioration of the smoking experience due to overheating of the mouthpiece part. The mouthpiece part realizes the inhalation of atomized smoke.

[0003] In the current heat-not-burn cartridge, after use, the entire cartridge is discarded, so there is a problem of high usage cost.

[0017] Hereinafter, the present invention will be described in more detail with reference to the accompanying drawings using specific embodiments. Here, similar elements in different embodiments are assigned the same reference numerals for related similar elements. In the following embodiments, many detailed descriptions are provided to better understand the present application. However, those skilled in the art can easily recognize that some of these features may be omitted in different situations or replaced by other elements, materials, or methods. In some cases, some operations related to the present application are not shown or described in the specification, which is to avoid being obscured by too much description of the core part of the present application. For those skilled in the art, based on the description in the specification and the general technical knowledge of those skilled in the art, they can fully understand the related operations, so there is no need to describe these related operations in detail.

[0018] Also, the features, operations, or characteristics described in the specification can be combined in any suitable manner to form various embodiments. Also, each step or operation in the description of the method can be changed or adjusted in an obvious manner to those skilled in the art. Therefore, the various sequences in the specification and drawings are for clearly describing specific embodiments and do not mean an essential sequence unless specifically described.

[0019] In this specification, the numbers assigned to components themselves, such as "first", "second", etc., are only used to distinguish the described objects and have no order or technical meaning. In the present application, "connection" and "coupling" include direct connection and indirect connection (coupling) unless otherwise specifically described.

[0020] In one embodiment, an atomizing device is provided. The atomizing base material used in this atomizing device is a heat-not-burn cartridge, and since this atomizing device can use a heat-not-burn cartridge that only includes a tobacco part, the hollow cooling part and the mouthpiece part of the conventional heat-not-burn cartridge are omitted, reducing the usage cost of the heat-not-burn cartridge. In addition, this atomizing device has a detachable structure of the plug-in type, and the heat-not-burn cartridge can be quickly replaced by insertion and extraction, improving the replacement efficiency of the heat-not-burn cartridge and thus improving the user experience.

[0021] Referring to FIGS. 1 to 5, the atomizing device of this embodiment mainly includes a first housing 1, a heating body 2, and a second housing 3. The first housing 1 and the heating body 2 are fixedly connected to form a single assembly. The first housing 1 and the second housing 3 are detachably connected. The first housing 1 and the second housing 3 have a connected state and a separated state. In the connected state, the first housing 1 and the second housing 3 are abutted, and the heating body 2 is inserted into the second housing 3. In the separated state, the first housing 1 and the second housing 3 are separated, and the heating body 2 is pulled out from the second housing 3 and separated from the second housing 3. The heating body 2 is for detachably attaching an atomizing base material 7 that only includes the tobacco part of a conventional heat-not-burn cartridge. In the connected state, the atomizing base material 7 is inserted into the second housing 3 together with the heating body 2, and the user can suck and use it. In the separated state, the atomizing base material 7 is separated from the second housing 3 together with the heating body 2, and it is also possible for the used atomizing base material 7 to be separated from the heating body 2. Thus, it can be replaced with a new atomizing base material 7 and used.

[0022] The first housing 1 belonging to the upper cover structure is provided with a mouthpiece 11 at one end, and the other end opposite to the mouthpiece 11 is fixedly connected to the heating body 2. A protruding connection part 12 is provided at the other end of the first housing 1 opposite to the mouthpiece 11. The connection part 12 is a sleeve structure having a mounting hole communicating with the mouthpiece 11. One end of the heating body 2 is inserted and fixed into the mounting hole of the connection part 12. The heating body 2 may be engaged in the mounting hole of the connection part 12 by a fitting method by press-fitting, or may be fixed in the mounting hole of the connection part 12 by screw connection.

[0023] In this embodiment, the first housing 1 is provided with a protruding connecting portion 12. The connecting portion 12 can not only be used to permanently attach the heating element 2, but can also be inserted into the second housing 3 when connecting the first housing 1 and the second housing 3. This enables positional restriction and fixing between the first housing 1 and the second housing 3.

[0024] In other embodiments, a recessed connecting portion may be provided at the other end of the first housing 1 opposite to the suction port 11. The recessed connecting portion has the structure of a mounting hole, and one end of the heating element 2 is inserted and fixed into the recessed connecting portion, thereby achieving not only a fixed connection between the heating element 2 and the first housing 1, but also communication between the heating element 2 and the suction port 11.

[0025] In this embodiment, the heating element 2 is a heating tube, and the heating tube has a heating chamber 21 that penetrates the heating tube, and the heating chamber 21 is used to attach the atomizing substrate 7 by inserting it. The heating tube is a metal structure that can be heated in order to achieve circumferential heating of the atomizing substrate 7 inside the heating chamber 21.

[0026] The depth of the heating chamber 21 is the same as or slightly greater than the length of the atomizing substrate 7. For example, if the atomizing substrate 7 is 10-14 mm long, setting the depth of the heating chamber 21 to 10-15 mm allows the entire atomizing substrate 7 to be housed within the heating chamber 21, enabling the heating chamber 21 to heat the entire atomizing substrate 7, which is advantageous for improving heating and atomization efficiency.

[0027] The first housing 1 may be made of plastic or other material that has a heat-shielding effect so that the heat from the heating element 2 is not transferred to the suction opening 11, thereby preventing the user from getting burned.

[0028] In this embodiment, the second housing 3 is the main body structure of the atomizing device, and an insertion groove 31 extending into the interior of the second housing 3 is provided at the upper end of the second housing 3 (the end of the second housing 3 facing the first housing 1). The inner diameter and depth of the insertion groove 31 are matched to the outer diameter and length of the heating element 2, allowing the heating element 2 to be inserted into the insertion groove 31.

[0029] Here, since the depth of the insertion groove 31 is slightly greater than the length of the heating element 2, the connection portion 12 of the first housing 1 and the heating element 2 can be inserted into the insertion groove 31, thereby connecting the first housing 1 and the second housing 3 so that their end faces are in contact with each other, resulting in a better sealing connection effect. In addition, since the entire heating element 2 is located within the insertion groove 31, heating of the heating element 2 becomes easier, as does maintaining the temperature of the heating element 2, improving heating efficiency.

[0030] In another embodiment, when a portion of one end of the heating element 2 is inserted into the first housing 1, the majority of the heating element 2 is located within the insertion groove 31, which also enables heating of the atomizing substrate 7.

[0031] In this embodiment, the second housing 3 may comprise an outer housing 3a with an insertion opening and an inner housing 3b having a cylindrical structure with one end open and the other end closed, wherein the inner housing 3b divides the space within the outer housing 3a into an insertion groove 31 and a housing chamber 32 that is aligned with and communicates with the insertion opening of the outer housing 3a. The outer housing 3a and the inner housing 3b may be fixedly connected by engagement connections, screw connections, etc., or they may be an integrated structure.

[0032] Of these, an air intake hole is provided at the bottom of the insertion groove 31, and an air intake port is provided at the bottom or side of the outer housing 3a. The air intake port, the housing chamber 32, the air intake hole, and the insertion groove 31 are in sequential communication, allowing outside air to flow into the heating chamber 21 of the heating element 2, i.e., into the atomizing substrate 7.

[0033] In this embodiment, the heating element 2 may be a metal tube that can be heated by electromagnetic induction. The housing chamber 32 of the second housing 3 is provided with an electromagnetic induction coil 4 that surrounds the circumferential outer side of the insertion groove 31. When the heating element 2 is inserted into the insertion groove 31, the electromagnetic induction coil 4 surrounds the circumferential outer side of the insertion groove 31. After the electromagnetic induction coil 4 is energized, it forms an induced magnetic field to heat the heating element 2, and the heating element 2 transfers the thermal energy generated by electromagnetic induction to the atomizing substrate 7 inside the heating element 2, burning the tobacco and generating smoke.

[0034] The electromagnetic induction coil 4 may be attached and fixed to the outer wall of the inner housing 3b, that is, fixed to the side wall located in the housing chamber 32 of the inner housing 3b. By attaching the electromagnetic induction coil 4 to the outer wall of the inner housing 3b, radial and axial alignment between the electromagnetic induction coil 4 and the heating element 2 can be made easier, and the heating efficiency of the heating element 2 can be ensured.

[0035] In other embodiments, a mounting bracket may be provided in the housing chamber 32 of the second housing 3, and the electromagnetic induction coil 4 can be attached to the mounting bracket and aligned radially and axially with the insertion groove 31.

[0036] In this embodiment, the heating element 2 is heated using an electromagnetic induction coil 4, achieving non-contact heating with a gap between them. Since the heating element 2 does not require connection to a heat source, the heating element 2 and the first housing 1 can be fixedly connected to form a single assembly. That is, the heating element 2 can be inserted into and removed from the insertion groove 31 by connecting and separating the first housing 1 and the second housing 3, thereby facilitating the replacement of the atomizing substrate 7.

[0037] In this embodiment, the first housing 1 and the second housing 3 can be fixed together by magnetic attraction. A first magnetic attraction portion 13 is provided at the end of the first housing 1 facing the second housing 3, and a second magnetic attraction portion 33 is provided at the end of the second housing 3 facing the first housing 1. The first magnetic attraction portion 13 and the second magnetic attraction portion 33 may be two magnetic blocks with opposite poles, or one of the first magnetic attraction portion 13 and the second magnetic attraction portion 33 may be a magnetic block and the other a metal block that can be magnetically attracted. In either case, the first magnetic attraction portion 13 and the second magnetic attraction portion 33 can be magnetically attracted to each other.

[0038] The first magnetic adsorption part 13 is fitted onto the end face of the first housing 1 facing the second housing 3, or is located inside the first housing 1 and is positioned close to the end face of the first housing 1 facing the second housing 3. Similarly, the second magnetic adsorption part 33 is fitted onto the end face of the second housing 3 facing the first housing 1, or is located inside the second housing 3 and is positioned close to the end face of the second housing 3 facing the first housing 1. The first magnetic adsorption part 13 and the second magnetic adsorption part 33 are positioned in alignment with each other, and the magnetic attraction force between the first magnetic adsorption part 13 and the second magnetic adsorption part 33 allows the first housing 1 and the second housing 3 to be fixed in a manner that allows them to be inserted into and removed from each other.

[0039] The first housing 1 and the second housing 3 are fixed together by magnetic attraction, and the magnetic attraction automatically completes when the user brings the first housing 1 and the second housing 3 close together, thereby improving the user experience by making it easier to attach and detach the first housing 1 and the second housing 3.

[0040] In other embodiments, a detachable fixed connection can be achieved between the first housing 1 and the second housing 3 by means of an engagement connection, a screw connection, or the like.

[0041] In this embodiment, the first housing 1 and the second housing 3 of the atomizing device have both a connected state and a separated state.

[0042] Referring to Figure 2, in the connected state, the first housing 1 and the second housing 3 are connected by magnetic attraction, the atomizing substrate 7 (including only the tobacco portion) is installed in the heating chamber 21 of the heating element 2, and the heating element 2 is inserted into the insertion groove 31 of the second housing 3. In this state, the electromagnetic induction coil 4 surrounds the outside of the heating element 2 in the circumferential direction, and the heating element 2 can be heated by energizing the electromagnetic induction coil 4. By heating the heating element 2, the atomizing substrate 7 is burned from the circumferential direction, generating smoke that can be inhaled.

[0043] Referring to Figure 3, in the separated state, the first housing 1 is separated from the second housing 3, and the first housing 1 separates from the second housing 3 by moving the heating element 2 in conjunction with it. In this state, the user can replace the atomizing substrate 7 inside the heating element 2, remove the used atomizing substrate 7 after baking, and install a new atomizing substrate 7.

[0044] In this embodiment, the atomizing device and electronic atomizing device have a first housing 1 connected to a heating element 2, and the first housing 1 is provided with a mouthpiece 11 that communicates with the heating chamber 21. As a result, the mouthpiece 11 in the first housing 1 can replace the mouthpiece portion of a conventional heated non-combustion type cartridge, and since the mouthpiece 11 is part of the first housing, it can be separated from the tobacco portion, eliminating the need for the hollow cooling portion of a conventional heated non-combustion type cartridge. This allows the atomizing substrate 7, which includes only the tobacco portion, to be attached to the heating chamber 21 of the heating element 2 of this atomizing device, significantly reducing the user's operating costs. Furthermore, the assembly consisting of the first housing 1 and the heating element 2 and the second housing 3 form a plug-in type detachable connection, making it easy to replace the atomizing substrate 7.

[0045] In one embodiment, a heating sheet may be attached to the outer wall of the heating element 2, and the heating sheet will have a resistance heating structure, which will convert electrical energy into thermal energy. The heating sheet is provided with a first electrical connection contact, and a second electrical connection contact corresponding to the position of the first electrical connection contact is provided in the insertion groove 31 of the second housing 3, and the second electrical connection contact is connected to a power source. After inserting the assembly consisting of the first housing 1 and the heating element 2 into the second housing 3, the first electrical connection contact and the second electrical connection contact come into contact and are electrically connected, enabling power supply by insertion of the heating sheet. By using a heating element 2 with a heating sheet, it is also possible to heat and bake the atomizing substrate 7 inside the heating element 2.

[0046] In one embodiment, the heating element 2 may have a rectangular tubular structure, and accordingly, the electromagnetic induction coil 4 can be provided as a structure wound along the rectangular tube to achieve electromagnetic heating of the heating element 2.

[0047] Referring to Figure 5, in one embodiment, the heating element 2 is a heating tube, one end of the heating tube is connected to the connection portion 12 of the first housing 1, and the other end of the heating tube is provided with a slot 22 extending axially from the end face of the tube wall of the heating tube, and the slot 22 may extend to a position close to the connection portion 12. The heating tube may be provided with one slot 22, or with multiple slots 22, for example, with two symmetrical slots 22.

[0048] The heating tube is provided with slots 22 to allow for elastic deformation in the radial direction, and the heating tube can form a clamping force to fix the atomizing substrate 7 in the heating chamber 21. Furthermore, the heating tube is configured to be expandable in the radial direction, making it easy to remove the atomizing substrate 7.

[0049] Of course, it is not necessary to provide a slot 22 in the heating tube, and since the atomizing substrate 7 shrinks in volume after heating, when replacing the atomizing substrate 7, the atomizing substrate 7, whose volume has shrunk, can be removed from the heating chamber 21 by swinging the opening of the heating element 2 downwards.

[0050] In one embodiment, a slot 22 may be provided in the heating element 2, and the inner diameter of the heating chamber 21 may be set to be slightly smaller than the outer diameter of the atomizing substrate 7 in its unheated, unused state. This allows the atomizing substrate 7 to be more securely mounted in the heating chamber 21 after a new, unused atomizing substrate 7 is placed in the heating chamber 21, as the atomizing substrate 7 with a larger outer diameter is held between the heating element 2. In this way, the atomizing substrate 7 can not be prevented from sliding out when the first housing 1 and the second housing 3 are combined, and the heating tube and the atomizing substrate 7 are brought into sufficient contact, improving the heat transfer efficiency, and thus improving the firing efficiency of the atomizing substrate 7 by the heating tube.

[0051] Referring to Figure 6, in one embodiment, a slot 22 is provided in the heating element 2 (heating tube), and a radially protruding pressing portion 311 may be provided on the inner wall of the insertion groove 31 of the second housing 3. For example, multiple hemispherical protrusions may be provided inside the insertion groove 31, or multiple axially extending convex ribs may be provided. The protruding pressing portion 311 may have a finely protruding structure, and when the heating tube is inserted into the insertion groove 31, the protruding pressing portion 311 presses the heating tube, thereby pressing and tightening the atomizing substrate 7 radially. That is, the heating tube is brought into sufficient contact with the atomizing substrate 7, improving the heat transfer efficiency, and thus improving the firing efficiency of the atomizing substrate 7 by the heating tube.

[0052] In one embodiment, radially protruding position limiting portions may be provided on the inner wall of the heating chamber 21 of the heating element 2. For example, multiple hemispherical protrusions may be provided inside the heating chamber 21, or multiple axially extending convex ribs may be provided. These protruding position limiting portions may have a finely protruding structure. When the atomizing substrate 7 is installed in the heating chamber 21, the protruding position limiting portions press against the atomizing substrate 7, thereby limiting and fixing its position within the heating chamber 21 and improving the stability of installation and fixing of the atomizing substrate 7.

[0053] Referring to Figure 7, in one embodiment, the inner housing 3b has a cylindrical structure, and mounting portions 34 projecting radially are provided at the axial upper and lower ends of the inner housing 3b. The mounting portions 34 may be flange structures, and an electromagnetic induction coil 4 is fitted onto the outer surface of the inner housing 3b, and the electromagnetic induction coil 4 is axially restricted in position by the two mounting portions 34. By providing the mounting portions 34, the electromagnetic induction coil 4 can be mounted in a restricted position.

[0054] Referring to Figure 8, in one embodiment, an electronic atomizing device is provided, which differs from any of the embodiments described above in that it further comprises a circuit board 5 and a battery 6.

[0055] The electronic atomizing device of this embodiment comprises a circuit board 5, a battery 6, and an atomizing device of any of the embodiments described above.

[0056] The circuit board 5 and the battery 6 are mounted inside the second housing 3. Specifically, the circuit board 5 and the battery 6 are mounted inside the housing chamber 32 of the second housing 3 and are located in a different chamber from the heating element 2.

[0057] The circuit board 5 is electrically connected to the battery 6 and the electromagnetic induction coil 4, respectively. The battery 6 is configured to supply power to the circuit board 5 and the electromagnetic induction coil 4. The circuit board 5 is configured to control the on / off switching of heating by the electromagnetic induction coil 4. The circuit board 5 can also control the output of heating by the electromagnetic induction coil 4.

[0058] A charging socket electrically connected to the circuit board 5 may be provided at the end of the second housing 3 that is away from the first housing 1, and the charging socket can be connected to a mobile power supply or commercial power supply to replenish the power of the battery 6.

[0059] In the electronic atomizing device of this embodiment, the first housing 1 is connected to the heating element 2, and the first housing 1 is provided with a mouthpiece 11 that communicates with the heating chamber 21. Therefore, the mouthpiece 11 in the first housing 1 can be replaced with the mouthpiece portion of a conventional heated non-combustion type cartridge. Furthermore, since the mouthpiece 11 is separated from the tobacco portion as part of the first housing, the hollow cooling portion of a conventional heated non-combustion type cartridge is also unnecessary, and the atomizing substrate 7, which includes only the tobacco portion, can be attached to the heating chamber 21 of the heating element 2 of this atomizing device, thereby significantly reducing the user's operating costs. Moreover, the assembly consisting of the first housing 1 and the heating element 2 forms a plug-in type detachable connection together with the second housing 3, making it easy to replace the atomizing substrate 7.

[0060] The above explanation of the present invention using specific examples is intended to aid in understanding the present invention and does not limit it. For those skilled in the art to which the present invention pertains, several simple inferences, modifications, or substitutions can be made based on the concept of the present invention.
